Genera and Species of Araneidea. 179 



considerably the largest : tlie clypciis, which is retreating, is 

 clothed witli numerous fine pale hairs ; and the surface of the 

 cephalothorax is furnished with others both pale and dark, 

 and erect. 



The eyes are in the ordinary position ; they form very 

 nearly a square, the fore side being very slightly longer than 

 the hinder one ; the small central eye of each lateral row is 

 slightly within the straight line of the other two forming that 

 row, and is also a trifle nearer the hinder than the fore one of 

 these two ; the four eyes which form the front row are of a 

 dark shining greenish colour ; the two centrals are, like those 

 of most other species of the genus, far the largest ; the row 

 is curved, the curve being directed forwards. 



The legs are moderate in length and strength ; their relative 

 length is 3, 4, 2, 1 or 3, 4, 1, 2, the difference between those 

 of the first and second pairs being very slight ; they are of a 

 pale yellowish colour, irregularly marked and banded Avitli 

 dark brown, and hairy, numerous short adpressed hairs of a 

 gi-eyish white being mixed with others dark-coloured and 

 erect : the metatarsi of the third pair are furnished with a tuft- 

 like group of bristly black hairs on either side ; the tibiaj and 

 metatarsi are also furnished with spines. 



The^:>a/^^/ are short and similar to the legs in colour. The 

 cubital and radial joints are short, the latter being the longest ; 

 they arc furnished pretty thickly with greyish-white hairs, 

 especially on the inner sides of the radial and on the digital 

 joints ; these latter are oval, and of moderate size : the radial 

 joint has a small tapering pointed projection at the extremity 

 of its outer side. The palpal organs appeared to be of very 

 simple structure, and to consist of a largish oval corneous 

 lobe. 



The falces are small, conical, placed far back behind the 

 frontal margin, and are of a yellowish-brown colour. 



The abdomen is of an elongated oval form and rather flat- 

 tened ; its upperside is furnished with an epidermis, which is 

 continued laterally on either side to an extent considerably ex- 

 ceeding the width of the abdomen, and of a semioval or ellip- 

 tical form ; the outer portion of this epidermis on either side is 

 capable of being depressed and folded round beneath the ab- 

 domen, or elevated and expanded to its full width, after the 

 manner of wings. The whole of the epidermis is densely 

 covered with short scale-like hairs, which give the different 

 tints and hues to the abdomen ; the portion which covers the 

 abdomen itself is striped longitudinally for rather more than two 

 thirds of its length alternately with scarlet and greyish green, 

 the latter reflecting brighter green and blue metallic hues :
